UNITED STATES PATENT orrron,

Specification of Letters Patent.

Patented July 24, 1906.

Application filed ry 19, 1906. Serial No. 801.763.

170 alt whom, it may concern:

Be it known that I, THOMAS G HUNT, a citizen of the United States of America, and resident of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Im rovements in Pin-Tongues, of which the 0 owing is a specification.

This invention relates more particularly to pin-tongues for pin-joints, so called-such, for example, as are used in conjunction with cufi-pins, brooches, or other analogous articles of jewelry, and it consists, essentially, of an inte ral or one-piece pin-tongue having its hea or joint end provided with oppositely-disposed short pintles or pivot-pins adapted to be movably mounted in the ears of the brooch or other pin and also having lateral lugs arranged to contact with the inner edges of said ears to form a somewhat resilient or yielding connection.

In my invention the complete in-tongue, including the pintles and lateral or stop members, are all fashioned from alank out or ressed out of sheet metal.

n the accompan g drawings, Fi e 1 is an enlarged si e e evation of a on -pin, in partial section, provided with my improved Fi 2 is, a plan view of the lank from whic the pin is formed, and Fig. 3 is an enlarged horizontal sectional view taker. on line :0 z of Fig. 1.

A. in the drawings represents one form of pin provided with my improved pin-tongue a. he pin may have any suitable back member, as b, and provided, say, with a pair of integral ears 0 c and catch member d, substantia ly as common.

The pin-tongue a, is formed from a sheetmetal blank m, Fig. 2. The blank has oppositely-located members a and lateral end lugs or steps a, all being integral, as before stated. The stem portion of the pin is converted by suitable tools into the cylindrical shank 8, having a shar ened point. The members a are also made round cross-sectionally and preferably slightly beveled or havin the form of a truncated cone, as shown enlarged at a, in Fig. 3': The rear or joint end of the pin-tongue member a'is subsequently bent to a hook-shaped form, (see Fig. 1,) the device thenbeing completed.

in applying my improved pin-tongue a the two laterallyertforatedears 0 of the back member I; are st separated or spread apart. The pin-tongue is next positioned between them, the pintles a then re istering with the holes therein, followed by ing the ears inwardly until they assume a vertical position, the intles at the same time readily entering said oles, thcreb pivoting the member a therein, the inner ace of the lugs a then being contiguous to the inner ed es 0 of the ears 0. (See also Fig. 3.)

use the member a; may be swung downwardly; say, to the full-line position, Fig. 1, at which instant the lugs a engage or contact with both the said inner edges 0 of the ears and forms a normal limit-stop for the pin tongue. The resiliency of the pin permits it to be further depressed, so as to engage the catch (1, the corres onding position being indicated by dotted 'nes in said Fig. 1.

It will be seen that the lugs a serve to maintain the pin a in position laterally, so that it will swing in a practically true path and without sidewise movement, thus guiding the free end of the shank s to the catch in a more positive and efficient manner.

I claim as my invention and desire to secure b United States Letters Patent- 1. an improved article of manufacture, a pin-tongue having its rear or joint end portion bent and terminating in-lateral lugs integral therewith.

2. An integral or onepiece pin-tongue having its rear or joint end portion bent at an angle with the stem and provided with oppositely-disposed lateral pintle members and oppositely-located lateral lugs, substantially as described and for the purpose set forth.

3. The combination with a pin-back having a pair of parallel laterally-separated ear members, of a swinging pin-tongue a-havin integral intles a mounted in said ears an rovide with o ositely disposed inte al ugs a arran e to engage the inner e ges of said ears, w ereby increased tension is imparted to the pin-tongue, substantially as described.

Signed at Providence, Rhode Island, this 16th day of February 1906.
